4 weeks on treatment... now what?

ok, well i've had my 2 clowns and coby in a QT tank for about 4 weeks now... treating for ich.. incase you didnt know.
my 29 DT is still fishless.

what should i do now? ( aint the treatment for any fish about 3-4 weeks?)

cant put the fish back in the DT since not 6 weeks since i took them all out yet...( or can i?)
how can i add them back so that they dont get stressed so much?
(still waiting for 6 weeks though unless of course its better to put them back, i mainly need to know what to do now with them)

 

forgot to mention a little background for people who dont know... Had ich, some fish died, i took the survivors and put them in my QT. Tore my DT tank, washed everything with fresh water( filter, sand, rock, tank.. everything) but got adviced that this wouldnt get rid of ich in tank anyways so... im still waiting the 6 weeks anyways, put it back, and now its been 4 weeks since i tore it down and now cycled again.... and now the main question is above.

 

what are ur param?

 

ammonia 0
nitrates 0
ph 8.4
temp. 78degrees

 

i dont see y not... ur param are fine... do the fish still have visible marks?

 

um.. i do see 1 or 2 little dots in one clown. they are not all that swimy but im guessing its from the stress caused by copper. what do u think?

 

anyone?

 

no takers?

 

really???:-/

 

come on people... need little help here.
